CLASS REQUIREMENTS

ENGINE:
Engine swaps (e.g., B Series with B Series) permitted; however,
OEM engine mounting points must be utilized. Engine swap (e.g.,
B Series to a K Series) permitted provided engine swap kits are
commercially available and approved by OGS in advance. Engine
must be from same manufacturer as body. Engine must be
overhead-cam, production-based design. Maximum two power
adders. Redundant power adders, such as a dual stage nitrous
system, will be counted as one power adder. Engine must be in
stock, transverse configuration. Dry sump oil system or external oil
pumps prohibited unless OEM equipped and engine is using
complete OEM oiling system.

ENGINE CONTAINMENT DEVICE:
Engine diaper or catch-pan device to capture oil and debris in
event of engine failure mandatory. Where exhaust header passes
directly under oil pan, two-piece diaper may be utilized. FWD
vehicles using OEM manual-transmission case must also have
such a device for the transmission, to capture oil and debris in
event of transmission failure. If catch-pan device is used, catch pan
must employ minimum 2-inch-high lips on all sides. Lips must be
coved or curved inward, so as to contain oil in pan. Catch pan
must cover entire area below engine/transmission. Catch pan must
extend from radiator support to firewall and from framerail to
framerail. In all cases, lips must be adequate enough to contain oil
in the catch pan. Should a competitor spill excessive oil from the
catch pan and debris onto the track, he or she may be disqualified
from further competition at the sole and absolute discretion of the
event director until catch pan is upgraded, regardless of height of
pan lips or pan design.

EXHAUST:
Not required.

FUEL:
NHRA-accepted racing gasoline permitted. Injection of any other
fuel prohibited (e.g., methanol injection). See General Regulations 1:6.

Really 150 pounds for nitrous after 10 years of it being legal overnight it's 150 pound weight penalty?

TDautowerkes

Working headlights and tail lights have never been enforced. I agree with some of the rules but to keep the spirit of the class,%50 of intercooler must be exposed? Who determines what %50 is? We have downpipes coming out of the hood and wheels that stick out like roller skates.

d16z6Tcrx

50 lb for e85? crazy?

fmfkid250

*67mm and smaller turbos with larger than 83mm turbine wheel will be subject to 72 mm weight minimums.

Wow so there is no advantage of the $3500 6785 or the Borg Warner 67.7...wonder if Irev going to boot these turbos out of true street.

Abraham-ATS

iTrader: (1)

good thing im not done with both of our cars so i can adjust to the rules... they seem pretty fair as long as we enforce them for everyone!

01DC4

iTrader: (3)

*67mm and smaller turbos with larger than 83mm turbine wheel will be subject to 72 mm weight minimums.*

So is that 83.0 or 83.9mm?

crazes

maybe cause of FTW i think its based on..


well there is rocket e85 and pump e85 but i doubt few people are running it

TDautowerkes

so basically the changes were
1-50 lbs for ethanol based fuel.....
2-150 lbs for nitrous
3-%50 of intercooler must be exposed. What if you don't run an intercooler? should %50 of piping be shown?
4-headlights and tail lights must all work? or must all be in place? the track is lit well, and we rarely race at night.
5-race suit 3.2-15sfi must be used with all ethanol based cars.
6-10' wide maximum width of rim measured from where to where?

061000rr

iTrader: (2)

so it boils down to every car that was fast last year and set records now has to add 200+ lbs to there car so the slower guys can catch up.

crazes

yup.. guess closer racing makes for better entertainment. kind of pro mod

TDautowerkes

its not closer racing cause the rules apply to everyone..... The fast cars will always be the fast cars ....... the guys that are going fast are just more creative withe the rules and manage to find a way to work around them. Those rules arent gonna stop the fast guys from going fast.


what i would like to know is why limit wheel width, and why add 150 lbs for nbitrous when its been alowed since javier worked for NHRA,

061000rr

iTrader: (2)

so if you run sfwd but dont enter the triple crown points series you DONT have to add weight for any of the stuff listed as penaltys?

dturbocivic

the car will need to fit the rules of the class in order to enter. otherwise you might as well just enter quick 32

PRO1

thats why my red neck a$$ stays teh F*ck home

tepid1

I like these rules. They are mostly based around SAFETY. That's what's most important.

tepid1

# 4, 5, 6 are clearly for safety.

I will agree, I don't understand the whole intercooler being exposed, only using 9" wide tires, etc. I do see them trying to make the class tight and competitive, while keeping safety upmost important.

061000rr

iTrader: (2)

its been 1 working taillight for as long as ive been in this game. and not just import. pretty much every single league out there is only 1 tail light

boosted92snatch

I can understand the suit for the ethanol fuels but no wider than a 10" rim??? And intercooler must be shown cmon now they might as well make it a true street shoot out! And thats why i dont go to the NJ events(and the BS sound curfew). Its sfwd let them have what theyve always had and have some good racing!

d16z6Tcrx

this is f*cking stupid. rather than add these stupid *** rules just tell miller he"s an ******* and we dont want you at our events. it gets obscenely clear every year with these rule changes and then added tech checks to his or his customers cars that just make it painfully obvious you dont like the man. you add a 50lb weight penalty because his fuel works? 50lbs for fuel? fucck outta here

061000rr

iTrader: (2)

this isnt pointed at miller. alot of people are running c85 witch will also make them add 50lbs.

EDLOVA23

c85 here and now im on the search for a new SFI 3.2A/15 suit

2fastGSR

The headlight and taillight rules have ALWAYS been there. Whenever you race at night in the North East, the track staff will tell you to turn on your lights. I have even seen them stop people at Atco if they didnt have working taillights.

crazes

not going to lie its kind of funny.it almost looks like it but i doubt thats actually the reason behind it

K20Ahondas

Yo!! Relax. 50lbs is nothing. I remember when fuel had 100lb weight penalty when it came to race gas vs any kind of alcohol.

There are other e85 fuels out there besides our FTW. FYI
